title: Reverse Proxy
subtitle: How to use SCM-Manager with common reverse proxies
displayToc: true
---
SCM-Manager can run behind any reverse proxy, but a few rules must be respected.
The reverse proxy should not encode slashes and the `X-Forwarded-For` and `X-Forwarded-Host` headers must be send to SCM-Manager.
If the proxy uses a different protocol as the SCM-Manager e.g. https on proxy and http on scm-manager, the `X-Forwarded-Proto` header must be send too.
If `XSRF protection` is enabled on the SCM-Manager server, the cookie has to be `HttpOnly=false` and must not be modified.
## nginx
```nginx
# set required forward headers
proxy_set_header X-Forwarded-Host $host:$server_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# if https is used make sure X-Forwarded-Proto header is send
proxy_set_header X-Forwarded-Proto $scheme;
# assuming scm-manager is running on localhost at port 8080
location /scm {
proxy_pass http://scm:8080;
}
```
## Apache
If you use `VirtualHost` sections, please make sure to put the directives `AllowEncodedSlashes`, `RequestHeader`,
`ProxyPass`, and `ProxyPassReverse` into the same section as the `Location` for SCM-Manager.
```apacheconf
# Ensure mod_proxy and mod_proxy_http modules are loaded
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
# avoid encoding of slashes
AllowEncodedSlashes NoDecode
# if https is used, make sure X-Forwarded-Proto is send
RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
RequestHeader set "X-Forwarded-SSL" expr=%{HTTPS}
# assuming scm-manager is running on localhost at port 8080
ProxyPass /scm http://localhost:8080/scm nocanon
ProxyPassReverse /scm http://localhost:8080/scm
<Location /scm>
Order allow,deny
Allow from all
</Location>
```
### Notes
* Setting ProxyPassReverseCookiePath would most likely cause problems with session handling!
* If you encounter timeout problems, please have a look at [Apache Module mod_proxy#Workers](http://httpd.apache.org/docs/current/mod/mod_proxy.html#workers).
## HAProxy
```apacheconf
backend scm
# use http as proxy protocol
mode http
# sets X-Forwarded-For header
option forwardfor
# check if scm is running
option httpchk GET /scm/api/v2
# assuming scm-manager is running on localhost at port 8080
server dcscm1 localhost:8080 check
# sets X-Forwarded-Host header
http-request set-header X-Forwarded-Host %[req.hdr(Host)]
# sets X-Forwarded-Proto to https if ssl is enabled
http-request set-header X-Forwarded-Proto https if { ssl_fc }
```
